Basal-like breast cancers : characterization and therapeutic approaches

Khalil, Tayma. January 2008 (has links)
Background. Both basal-like subtype and BRCA1-related breast cancers tend to have a poor overall prognosis and lack of effective treatments. Given that the lung cancer drug gefitinib and the leukemia drug dasatinib inhibit proteins also belonging to the molecular signature of this subtype, we and others hypothesized that they might be useful therapies for those two breast cancer subgroups. / Methods. Eight breast cancer cell lines were characterized by immunohistochemistry and western blotting and were treated with both drugs. Response was measured by using the sulphorhodamine B (SRB) assay. / Results. Two out of six basal-like cell lines were sensitive to gefitinib and five of six to dasatinib. BRCA1-related breast cancers were also responsive to dasatinib (three out of four). Moreover, EGFR and caveolin-1 act as markers for dasatinib sensitivity, but do not appear to be the primary targets of this drug. The presence of SRC but not ABL is necessary to achieve a response to dasatinib. / Conclusion. Dasatinib is more effective in the treatment of basal-like breast cancers than gefitinib and acts by inhibiting SRC and other molecules that are yet to be determined.

Avaliação da eficácia e segurança da imunoterapia tópica com imiquimode creme 5% no tratamento do carcinoma basocelular nodular periocular / Evaluation of efficacy and safety of topical administration of 5% imiquimod cream for periocular nodular basal cell carcinoma

Macedo, Erick Marcet Santiago de 28 January 2013 (has links)
OBJETIVO: Avaliar a eficácia e segurança da imunoterapia tópica com imiquimode creme 5% no tratamento do carcinoma basocelular nodular periocular. MÉTODOS: Pacientes com carcinoma basocelular confirmado por biopsia e com contraindicação clínica para a cirurgia reconstrutiva devido ao alto risco ou que recusaram a cirurgia por razões estéticas ou fobia foram incluídos no estudo. O tratamento foi iniciado após treinamento do paciente e de acompanhante. A posologia foi de 5 vezes por semana por 8 a 16 semanas. Acompanhamento quinzenal foi realizado durante a vigência do tratamento com questionário, exame biomicroscópico, medida da acuidade visual e documentação fotográfica. As características clínicas das lesões foram mensuradas através do software ImageJ. Após 12 semanas do fim da terapia, uma nova biópsia na região da lesão foi guiada por fotografia. O seguimento dos pacientes foi semestral, após fim do tratamento, com biópsias anuais da região até o presente momento. RESULTADOS: 19 foram tratadas. A taxa de cura histológica foi de 89,5% após três meses do final do tratamento, e de 84,2% nos três anos de seguimento (39,5 meses). A taxa de cura histológica em três anos foi de 100% para lesões menores que 10 mm, e de 81,8% para lesões maiores que 10 mm. De uma forma geral, os efeitos colaterais da medicação foram mais frequentes durante as oito primeiras semanas de tratamento. Quanto menor foi a distância da lesão à margem palpebral, maior foi chance de o paciente desenvolver ectrópio no tratamento (p = 0,045). Assim, como quanto maior foi a inflamação, maior foi a chance de desenvolver ectrópio, dor e edema durante o tratamento (p = 0,017, p = 0,016 e p = 0,044, respectivamente). CONCLUSÕES: Imiquimode creme 5% mostrou-se eficaz para o tratamento alternativo do carcinoma basocelular periocular, principalmente em lesões menores que 10 mm. Em adição, demonstrou um interessante efeito neoadjuvante sobre as lesões maiores que 10 mm que não foram curadas. Mostrou-se um tratamento seguro; entretanto, um cuidado maior deve ser dado às lesões próximas à margem palpebral devido ao maior risco de complicações e desenvolvimento de ectrópio / Objective: to evaluate the efficacy and safety of topical administration of 5% imiquimod cream in the treatment of periocular nodular basal cell carcinoma (BCC). Methods: Patients with periocular nodular basal cell carcinoma confirmed by biopsy and clinical contraindication to reconstructive surgery due to high risk or who decline surgery for aesthetic reasons or phobia were included in the study. The medication was applied once a day, five days a week for 8-16 weeks. Treatment was initiated after provision of patient and caretaker training. During treatment, patients were followed up twice a month with questionnaires, biomicroscopic examinations, measurement of visual acuity and photographic documentation. The clinical characteristics of the tumors were registered with the software ImageJ. Twelve weeks after the end of treatment, an image-guided biopsy of the tumor site was performed. Patients have since been attending follow-up visits every six months, and biopsies of the region are performed annually. Results: 19 tumors were treated with imiquimod. The average histological cure rate was 89.5% after 3 months at the end of the treatment and 84.2% after 3 years of follow-up (39.5 months). The 3-year histological cure rate was 100% for smaller tumors and 81.8% for larger tumors (>10 mm). In general, drug-related side effects were more frequent during the first 8 weeks of treatment. The smaller the distance between tumor and lid margin, the greater the probability of developing ectropion during treatment (p=0.045). Likewise, the more severe the inflammation, the greater the probability of developing ectropion, pain and edema during treatment (p=0.017, p=0.016 and p=0.044 respectively). Conclusion: Topical administration of 5% imiquimod cream was found to be an efficacious and relatively safe alternative treatment for periocular BCC, especially for tumors smaller than 10 mm, with interesting neoadjuvant effects on uncured tumors larger than 10 mm. However, special care is required when treating tumors near the eyelid margin due to the risk of complications and development of ectropion
